Excellent, c'est exactement à quoi j' avais pensé

( avec en + un retour sur 2 voies )
J'ai d'ailleurs soumis cette solution ( voir ci-dessous ) directement à Allen and Heath. Je publierai leur réponse.

Hi,
I've got an idea. I couldn't test it 'cause I haven't received the mixer yet, so I let you to appreciate the solution. Does it woth testing it ?
I send all the drum stuff on two auxiliar buses ( aux 3 & aux 4 for instance ). I plug aux 3 & aux 4 out on two free line-in ( channel 15 & 16 for instance ). Consequentely, I can get a stereo signal from line-out 15 & 16 and send it directly into my recorder.
Advantage : I realise a "premix" of my drum with two lines out.
Drawbacks : I lost two channels on the mixer & two auxiliar lines.
Best regards,
Jean
